碳化锆

为了进一步发展和开发利用高温气冷堆，用碳化锆镀层替代碳化硅镀层制备新型的包覆燃料颗粒。

ZrC layers are used instead of silicon carbide ( SiC ) layers for fabricating a new type of coated fuel particle for the high temperature gas cooled reactor ( HTGR ) .

研究表明碳化锆镀层的密度随沉积温度而变化，反应气体中碳锆的原子数比值和氢氩流量比值影响碳化锆镀层性能和结构。

The density of the ZrC layer changed with deposition temperature . The effects of the atomic ratio of carbon and zirconium and the flowrate ratio of hydrogen and argon in the coating gas on the characteristics and structure of ZrC coating layer were studied .

以碳化锆为原料，采用碱熔-水洗-酸浸-结晶工艺制备氧氯化锆，制得的氧氯化锆产品中ZrO2含量达到36.20%。

Zirconium oxychloride with purity of 36.20 % was prepared from zirconium carbide by the process of alkali fusing , water washing , hydrochloric acid leaching and product crystallization .
